“…Follmann et al ( 2019) reported a broad-sense heritability (H²) of 0.93 for the 100-grain weight, while Barbosa et al (2021) found a narrow-sense heritability (h²) of 0.006, indicating a strong genetic influence. For the variables of crude fiber, mineral material, and palmitic acid, Bellinasso et al (2021) observed mean genotype heritability (h² g ) values of 0.26, 0.96, and 0.44, respectively. As for stearic fatty acid, oleic fatty acid, linoleic fatty acid, and linolenic fatty acid, this author noted broad-sense heritability (h² g ) values for total genotypic effects, with values of 0.82, 0.75, 0.78, and 0.53, respectively.…”

This study aims to select soybean lines with desirable nutraceutical characteristics under specific meteorological conditions in the selection environments. The experiment was conducted during the 2021/2022 harvest at Escola Fazenda, Regional University of the Northwest of the State of Rio Grande do Sul, located in Augusto Pestana- RS, Brazil. The experimental design was augmented blocks, with 27 populations of F2 generation, 118 lines of F5 generation, 70 lines of F8 generation, and 15 soybean cultivars as interim checks, arranged in three replications. The chemical composition of soybeans was evaluated using Near Infrared Spectroscopy - NIRS method to analyze various nutritional components. The IRC050 genotype exhibited a nutraceutical profile characterized by an increment in stearic fatty acid (STEAR) and reduction in fiber (FB) and mineral material (MM) contents. Among the F5 generation, the following genotypes were selected based on their nutraceutical traits: L174F5, L307F5, L322F5, L205F5, L190F5, L196F5, L219F5, L183F5, L301F5, L172F5, L198F5, L182F5, L319F5, L21F5, L188F5, L217F5, L302F5, L315F5, L36F5, L318F5, L211F5, L165F5, L321F5, and L179F5. The indirect selection of genotypes with higher levels of linoleic acid and protein was facilitated using the enzyme peroxidase.

“…According to Pipolo et al (2015), high temperatures during soybean grain filling contribute to the increase in oleic acid concentration, while lower temperatures increase the concentration of linoleic and linolenic acids. For industrial processing, the production of oils with greater oxidative stability is sought, that is, with higher oleic acid contents, and lower linoleic and linolenic acid contents, improving their usefulness at higher temperatures, for pharmaceutical purposes, cosmetics and industrial products such as biodiesel (Bellinasso et al, 2021;Figueiredo, 2017).…”

“…The MIII management demonstrated greater affinity with variables percentage of mineral material in the grain (MMG), percentage of stearic acid in the grain (AESTG) and number of branches (NB). The soybean grain is rich in minerals that are divided into macro and micronutrients, and the increase of these are of paramount importance in human and animal food (Bellinasso et al, 2021). For management MIV, the variables that stood out were: percentage of carbohydrates in the tissue (CHOT), which is positively influenced in the treatment, and neutral detergent fiber in the tissue (NDFT).…”

Background. The management of diseases in soybean crops demands a great economic cost with fungicide applications. Therefore, unnecessary or excessive applications can promote negative environmental results. Therefore, understanding the weather conditions and the development of diseases in the crop is essential to avoid the unnecessary use of fungicides, consequently reducing costs and ensuring the sustainability of the activity. Aim. The aim is to identify which yield components are quantitatively affected, and which aspects of the chemical composition of the grains are qualitatively influenced by fungicide management, in addition to relating the cost-benefit rate of sequential applications or previously stipulated management in the soybean crop, as well as their economic effects under water deficit conditions. Methodology. The trial was carried out using a randomized block design composed of 4 replications. The trial consisted of 5 kinds of fungicide management, defined by the time and number of applications, during the development cycle of the Lança cultivar, in the 2019/2020 crop season. Soybean agronomic traits and nutritional attributes were evaluated. Results. Unfavorable climate conditions contributed to the low rate of Asian rust infection during the soybean development cycle. The different kinds of fungicide management influenced soybean performance for the main agronomic variables studied. For the chemical composition of the grains, there was no statistical difference in relation to the different kinds of fungicide management. Implications. The results indicate that the management of fungicides must be carried out according to the meteorological conditions of the year of cultivation. Conclusion. Management without fungicide application maximized grain yield and promoted the highest economic return.

This work aimed to verify if it is possible to select soybean genotypes tolerant to diseases and water stress. The experimental design was randomized blocks (RBD), with thirty soybean genotypes, in four replications, totaling 120 experimental units. Evaluations were performed based on crop yield components and disease incidence in thirty soybean cultivars in field conditions. Analysis of variance was performed at 5% probability using the F test. Variables that showed significance were compared using Scott-Knott's grouping of means at 5% probability. Pearson's linear correlation coefficients were calculated between pairs of variables, with significance imposed by the t test at 5% probability. The Euclidean distances were calculated and the UPGMA grouping was performed to construct the genetic dissimilarity dendrogram, after which the biplot principal components were used to identify the association trend between variables and cultivars. It was possible to select soybean genotypes for grain production and disease tolerance in an environment with water stress. Cultivars M 5947 IPRO, TEC 6702 IPRO, M 6410 IPRO showed the highest grain yield. The cultivar TEC 6702 IPRO showed the best agronomic performance for morphological and productive characteristics, associated with the lowest incidence of diseases.
